I have used Gillette Sensor Excel For Women for quite a while, and I continue to use it, on and off. It has a nice, wide, non-slip handle, ergonomically designed and easy to hold in a wet hand, which makes me feel safer from getting cut. The razor heads, or cartridges, come with a special moisturizing slip that also has Aloe Vera and Vitamin E in it. They shave very nicely and smoothly. When a head becomes dull and no longer shaves well, it is easily replaced by a new one: you just press two buttons on the sides and the old head comes out; then you insert the new one instead. Replacement heads are sold in packs of 5, 10, 20, and more.
I like this tool, but the reason I do not use it exclusively is that the replacement heads are somewhat expensive. When I am on a tight budget and I see that they cost more than a larger pack of generic disposable razors, I go for generic ones.
